[Plugin: WooCommerce] Price not showing on single product page

I have set up WooCommerce on my wordpress site and it was working smoothly. But about a week ago, the price stopped showing up on the single product pages. The price shows up below thumbnails of products when they are listed, and in the related products box, but when you click on a single product, it doesn’t show up on that page. It is isn’t even being printed in the HTML.

Any ideas about how to solve this?

I have updated to the newest version of woocomerce 1.4.4.
